Study Notes
Problem-Solving and Algorithms
- Problem-solving involves any activity or task undertaken to achieve a specific goal or objective.
- Examples of problem-solving include packing a school bag according to a timetable, watching a favorite TV channel, going shopping, or going to a movie.
Algorithms
- An algorithm is a step-by-step procedure for solving a logical or mathematical problem.
- It involves dividing a problem-solving process into sequential steps.
Flowcharts
- A flowchart is a diagram that represents an algorithm or problem-solving process.
- It uses various symbols to represent the flow of a process.
- Flowcharts can be simple or complex, depending on the problem they represent.
Simple Flowcharts
- A simple flowchart involves only input, process, and output.
- It moves only in a vertical direction (top to bottom).
Decision-Making Flowcharts
- Decision-making flowcharts help make decisions based on logic.
- They have at least one decision symbol with two exit points (Yes/True and No/False).
- These flowcharts are used to raise a condition along with its solution.
Loop-Based Flowcharts
- Loop-based flowcharts involve a process repeated until a certain condition is met or fulfilled.
